      Thanks Joe and Rudy. That did it. I was way away from those settings. I
      was working OK, but had the zero about +66, the Gain at 2, and the slope was
      fairly high as well. It gave me a nice flat response - but also limited
      what I could see of the graph. Now I have what I need.
      You got me back on track.
      73,

      gain = 0, slope = 0.3, N Avg 5, Bins/Pixel = 7

      In cumulative, by "baseline" is about two major divisions up (20 db?) and in
      current, it is one major division above the bottom.
